CY22U1LCALGXC-00 is a dual-frequency programmable clock generator which belongs to the family of Clock/Timing- Clock Generators, PLLs, Frequency Synthesizers. This device is designed to provide greater flexibility in achieving system level timing requirements inclock design and integration.

CY22U1LCALGXC-00 provides two independent outputs that can be programmed to generate two different frequencies with two different clock sources. It can bring two chip-level clocking functions into one chip. The two output frequencies can be kept in lock through zero-delay clock distribution when used in the same system.

The CY22U1LCALGXC-00 provides both open-loop and closed-loop frequency synthesis. Two independent PLLs for each clock output allow for programmability of output frequency. The device is designed to simplify the clock tree in applications requiring multiple outputs. It eliminates the need for external dividers and buffers when generating multiple clock signals from a single reference.

Cy22U1LCALGXC-00 has several applications. It can provide both crystal and silicon oscillator outputs for microcontrollers and other devices. It is ideal for high-speed digital communication systems, such as the Ethernet and other industrial systems. Additionally, the device can be used in systems that require multiple clocks. It can also be used in resolver-type motor control systems to produce two-plane motor control signals.

This device works on a closed loop frequency synthesis topology. Oscillators are used to provide reference frequency which is divided to generate the internal reference clock. This internal reference is then directed to the PLL circuitry to achieve a precise output frequency. The PLLs use a variety of loopbandwidths which can be back-biased to reach lower values which allows the stabilization of the designed PLL loop bandwidth.

The phase- locked loops on the device make it possible to precisely lock the output frequencies to a reference frequency or to each other in Zero-Delay Clock mode. This means that the device can be used to synchronize multiple devices or to generate precise clock signals for different types of applications. With the out-of-the-box functionality, the device can work with a single reference, which simplifies the overall clock tree.

The CY22U1LCALGXC-00 also provides a wide supply voltage range of 1.8V to 3.3V, making it compatible with a wide range of consumer and industrial applications. It also has an operating temperature range of -40 to +85°C and is available in a 5mmx5mm LQFN-48 pin package.

CY22U1LCALGXC-00 is a highly integrated device with multiple outputs, programmability and synchronization capabilities. It is ideal for applications where multiple frequencies need to be generated from a single reference. With its wide operating range, it is suitable for a variety of consumer and industrial applications and is an ideal choice for system level timing requirements.
